RALEIGH
SINGLE FAMILY SPRAY IRRIGATION PERMIT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as
amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Elwood Dodson
Caswell County
FOR THE
construction and operation of a 360 GPD wastewater spray irrigation wastewater treatment and disposal
system consisting of a 1,200 gallon baffled septic tank, a 330 ft2 subsurface sand filter, a tablet
chlorinator, a 2,000 gallon storage/pump tank, and an 11,760 ft2 spray irrigation area to serve the Dodson
Residence, with no discharge of wastes to the surface waters, pursuant to the application received April 4,
1994, and in conformity with the project plan, specifications, and other supporting data subsequently filed
and approved by the Department of Environment, Health and Natural Resources and considered a part of
this permit.
This permit shall be effective from the date of issuance until March 31, 1999, and shall be subject
to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
1. Upon completion of construction and prior to operation of this permitted facility, a
certification must be received from a professional engineer certifying that the permitted
facility has been installed in accordance with this permit, the approved plans and
specifications, and other supporting materials. Mail the Certification to the Water Quality
Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC 27626-0535.
2. The Winston-Salem Regional Office, telephone number 910/896-7007, shall be notified at
least forty-eight (48) hours in advance of operation of the installed facilities so that an in-
place inspection can be made. Such notification to the regional supervisor shall be made
during the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday,
excluding State Holidays.
3. The spray irrigation facilities shall be effectively maintained and operated at all times so that
there is no discharge to the surface waters, nor any contamination of ground waters which
will render them unsatisfactory for normal use. In the event that the facilities fail to
perform satisfactorily, including the creation of nuisance conditions or failure of the
irrigation area to adequately assimilate the wastewater, the Permittee shall take immediate
corrective actions including those actions that may be required by the Division of
Environmental Management, such as the construction of additional or replacement
wastewater treatment and disposal facilities.
1

4. The issuance of this pen -nit shall not relieve the Permittee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
5. The sand media of the subsurface sand filter must comply with the Division's sand
specifications. The engineer's certification will serve as evidence that these specifications
have been met.
6. A leakage test shall be performed on the septic tank and dosing tank to insure that any
exfiltration occurs at a rate which does not exceed twenty (20) gallons per twenty-four (24)
hours per 1,000 gallons of tank capacity. The engineer's certification will serve as proof of
compliance with this condition.
7. If excavation into bedrock is required for the installation of the septic tank or sand filter, the
pit shall be lined with a 10 mil synthetic liner.
The residuals generated from these treatment facilities must be disposed in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management.
9. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
10. The following buffers shall be maintained;
a) 400 feet between wetted area and any residence or places of public assembly under
separate ownership,
b) 150 feet between wetted area and property lines,
c) 100 feet between wetted area and wells,
d) 100 feet between wetted area and drainageways or surface water bodies,
e) 50 feet between wetted area and public right of ways,
f) 100 feet between treatment/storage units and any wells, and
g) 50 feet between treatment units and property lines.
II. OPERATIQN AND MAINTENANCE REQUIREMENTS
The facilities shall be properly maintained and operated at all times.
2. A suitable vegetative cover of Kentucky 31 Tall Fescue shall be maintained.
3. Irrigation shall not be performed during inclement weather or when the ground is in a
condition that will cause runoff.
4. Adequate measures shall be taken to prevent wastewater runoff from the spray field.
5. The application rate shall not exceed .35 inches per week at an instantaneous application
rate not to exceed .09 inches per hour.
6. The facilities shall be effectively maintained and operated as a non -discharge system to
prevent the discharge of any wastewater resulting from the operation of this facility.
7. No type of wastewater other than that from the Dodson Residence shall be sprayed onto the
irrigation area.
S. In the event that the sprinkler heads fail to achieve the design diameter of 65 feet due to
obstructions, the obstructions shall be removed or the sprinkler heads shall be raised and
supported to such height that the design diameter is achieved.
2

9. No traffic or equipment shall be allowed on the disposal area except while installation
occurs or while -normal maintenance is being performed.
10. The Permittee is responsible for the operation and maintenance of the entire treatment and
disposal system including, but not limited to, the following items:
a. The septic tank shall be checked annually and pumped out as needed.
b. The tablet chlorinator shall be checked every week. Tablets shall be added so as to

be removed at the same interval as the septic tank is cleaned out.
d. The spray system shall be inspected weekly to make certain of the sprayers proper
operation, that the vegetative growth allows a proper spray pattern, that the soil is
assimilating the disposed treated wastewater with no surface runoff, and that no
objectionable odors are being generated.
11. The Permittee shall maintain and keep on site a legible log of the wastewater treatment
system's operation and maintenance activities, as set forth in the Operation and
Maintenance agreement between the Permittee and the Division of Environmental
Management.
III. MONITORING AND REPORTING REQUIREMENTS

surface and ground water protection will be established and an acceptable sampling
reporting schedule shall be followed.
2. The Permittee shall maintain records of all maintenance performed on the system and
irrigation area, as required in Condition 11.10 for a minimum of five years. This
information shall be provided to the Division of Environmental Management upon request.
3. Noncompliance Notification:
The Permittee shall report by telephone to the Winston-Salem Regional Office, telephone
number 910/896-7007, as soon as possible, but in no case more than 24 hours or on the
next working day following the occurrence or first knowledge of the occurrence of any of
the following:
a. Any process unit failure, due to known or unknown reasons, that renders the facility
incapable of adequate wastewater treatment, such as mechanical or electrical failures of
pumps, spray heads, etc.; or
b. Any failure of a pumping station or treatment facility resulting in a by-pass directly to
receiving waters without treatment of all or any portion of the influent to such station or
facility.
Persons reporting such occurrences by telephone shall also file a written report in letter
form within 15 days following first knowledge of the occurrence. This report must outline

municipal or regional sewerage system.
5. The spray irrigation field shall be fenced with at least a two strand wire fence.
6. Failure to abide by the conditions and limitations contained in this permit may subject the
